Fats and oils, important compounds in our diet, are naturally occurring esters and their structure … WebIn organic chemistry, esters are a common functional group. The basic structure of an ester consists of a carbon single bonded to carbon, double bonded to oxygen, and single bonded to oxygen. For the molecule below, the simple structure of an ester group is shown. The basic chemical formula of an ester is R-COOR’.
An ester is an organic compound where the hydrogen in the compound's carboxyl group is replaced with a hydrocarbon group. Esters are derived from carboxylic acids and (usually) alcohol. While carboxylic acid has the -COOH group, the hydrogen is replaced by a hydrocarbon in an ester. The chemical formula of an … See more Ethyl acetate (ethyl ethanoate) is an ester.
